In Mali, Malarial 5, which is an Improved Traditional Medicine (ITM) produced partly from the leaves of Lippia chevalieri, is used to treat the symptoms of uncomplicated malaria. The leaves of cultivated Lippia chevalieri can be used for the preparation of improved traditional medicines because they are of good quality. This paper focuses on the physicochemical control which showsthat the leaves of cultivated Lippia chevalieri contain less than 10% of moisture content. The total ash content was a little higher, and the acid insoluble ash was low. The best yields of extractions are obtained with water through infusion and decoction. Several chemical compounds including carotenoids, coumarins, mucilage, and flavonoids were revealed.
